Answer:
x = 4
Explanation:
3x - 4y = 36
5x + 2y = 8 ( multiply all by two )
3x - 4y = 36
10x + 4y = 16
13x = 52
Divide by 13
x = 4 hope this helps
1.) It's a parallelogram
area:
3.5 x 5.8 = 20.3
perimeter:
4 + 4 + 5.8+5.8 = 19.6
2.)It's a right triangle
<span> area:
</span> (6.92 x 11) ÷ 2 = 38.06
<span> perimeter:
</span> 6.92 + 11 + 13 = 30.96
3.) ...that looks like a square tbh xD
<span>area:
</span>4.4 x 3 = 13.2
<span>perimeter:
</span>2.4
4.) Trapezoid
Just make the equation look like this y = mx + b
So 3x + y =10 would equal y = -3x + 10
Given:
Street C is perpendicular to Street A and passes through (4, -6).
The equation of street A is:

To find:
The equation of street C.
Solution:
The equation of street A is:

On comparing this equation with slope intercept form
, we get

Slope of this line is -2.
We know that, the product of slopes of two perpendicular lines is always -1.




The slope of street C is
and it passes through the point (4,-6). So, the equation of street C is



Therefore, the point slope form of the street C's equation is
.
